Diffusion and Osmosis Review

Front

What is equilibrium in the context of cells?

Back

Equilibrium is the state when the concentration of water inside and outside of a cell is the same.

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

What is a solvent?

Back

A solvent is the substance in which a solute is dissolved.

Front

What is osmosis?

Back

Osmosis is the movement of water across a semi-permeable membrane.

Front

What does homeostasis mean?

Back

Homeostasis is the process by which a cell maintains a stable internal environment.

Front

What is the role of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell, helping to maintain homeostasis.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent.

Front

How does temperature affect diffusion?

Back

Higher temperatures increase the energy of molecules, leading to faster diffusion.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.
